JAMES HOLMES ROSEOEANS, OF CINOINN ATI, OHIO.

SCALE-INDICATOR.

SPECIFICATION forming part of Letters Patent No. 336,595, dated February 23, 1886.

Application tiled September 5, 1895. Serial No. 176,266. (No model.)

To all whom it may concern:

Be it known that I, JAMES H. RosEcRANs, a citizen of the United States, residing at Oincinnati, in the county of Hamilton and State of Ohio, have invented a new and useful Improvement in Scale-Indicators, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to an improvement in scale-indicators, designed to enable any person to read round notes without first going through the laborious process of learning all the principles connected with musical notation; and it consists in a chart or scale having a series of staffs corresponding to the various keys, and having the notes designated by syllables in their correct places in the staffs of the various keys, whereby the naine of any note in any key of a piece of music may be ascertained by ranging the corresponding keystaff of the chart or scale on the staff of the piece of music; and it further consists in the peculiar arrangement that will be more fully set forth hereinafter, and particularly pointed out in the claims.

In the drawings, Figure l is a perspective view of a tablet inscribed with my scale, the leaf having the scale Written or inscribed with the notes in the key of O being extended. Fig. 2 is a reverse view of the same. Fig. 3 is a perspective view with the leaves of the tablet so arranged as to display a number of scales, with the notes written in various keys. Fig. 4t is a front view showing the application of the scale-indicator to a piece of music.

A represents a tablet composed of a numher of cards or leaves, B, secured together by a pivotal central fastening-eye, O, so that the cards or leaves may be turned to extend either end of either of the cards to the right of the rest, as shown at Fig. l, the cards or leaves being each adapted to turn independently of the others. The ends of these cards are inscribed with musical staifs, two sizes of staffs corresponding to the different sizes of musical printing-types in most common usebeing on each end of the cards. The staffs on one end of a card or leaf are inscribed with notes designated by the syllables do, re, mi, fa, sol, dto., in their correct places in a certain keysay the key of C, as shown in Fig. l-and on the reverse side of said card are staffs inscribed with syllables written in the same key on the bass clef. A suitable number of these cards or leaves are used to furnish scales written in all the various keys, and the ends of said cards or leaves unoccupied by said scales may be inscribed with suitable directions or information useful to musical students.

In order to ascertain the names of all the notes in a staff in a piece of music written in the key of O, the corresponding key of my chart will be extended and ranged along the staff of the piece of music, from which it will appear that the note in the second space below the staff is si, the note on the first added line below the staff is do, the note in the first space below the staff re, and so on, and thus renders it possible for a person unacquainted with the principles of musical notation to read a piece of music, no matter how difficult or in what key it may be written.

I do not desire to be limited to the precise construction and arrangement of the chart or scale described and shown, as it is evident that it may be modified and altered without departing from the spirit of my invention.

Having t-hus described my invention, I claiml. The tablet composed of a series of cards or leaves arranged to turn independently, said cards being inscribed with staffs having signatures corresponding to the various musical keys, and having the notes designated in the correct places in the staffs by syllables, for the purpose set forth, substantially as described.

2. The tablet composed of a series of cards or leaves, said cards being inscribed on one side with staffs having signatures corresponding to the various keys, and having the notes written in the treble clef designated in the correct places in t-he staffs by syllables, the reverse sides of the cards or leaves having corresponding staffs in which the notes in the bass clef are similarly designated, substantially as described.

In testimony that I claim the foregoing as my own I have hereto afiixed my signature in presence of two witnesses.

JAMES HOLMES ROSEORANS.
